For ebook returns (and I've only ever returned two because of of formatting issues), I've always done it over the phone, talking to a human. And the customer service reps in those two instances stayed on the phone with me until I provided location numbers and they were able to see the same errors I was seeing. Both reps also indicated they were pulling the books in question from the catalog while the issues were taken up with the publisher/author. I was able to verify that the book was no longer available for purchase after the phone call.
